San Diego Academy is a private coeducational K-12 school in the Seventh-day Adventist school system. As set forth in its constitution and bylaws, San Diego Academy is governed by a Board of Trustees composed of pastors and elected lay people of the constituent Seventh-day Adventist churches, parents, and alumni. The school operates under the auspices of the Southeastern California Conference of Seventh-day Adventists Office of Education.
San Diego Academy provides Christian education for K-12 young people in the Seventh-day Adventist churches located in the greater San Diego metropolitan area. The churches represented on the Board of Trustees are constituent members of the school and support it by giving an amount equal to 10.5% of their tithe income each year. Churches encourage each child in their church to attend. Some churches give added assistance to worthy families to make it financially possible for their students to attend.
San Diego Academy had its beginnings in 1899 when W. M. Healey, pastor of the Adventist church, rented a store at 17th and K Streets. Seventeen students began their Christian education with Robert Sanders and his wife serving as teachers.The school functioned as an elementary school and then a junior academy until 1930 when it became a full 12-grade school.
